Hello Brilliant People!! I am having an issue. I just purchased a 2009 Jayco popup and its canvas needs some work. The previous owner decided it would be a good idea to put Flex seal all over the vinyl and seams. Imagine a kindergartener given a paintbrush and Elmer's glue, this is where we are. I need to get this stuff off of it. Does anyone have any idea how I can do so? In a perfect world I would be replacing the canvas, but seeing as there is a year wait, that is not going to happen. On top of the Flex seal, The window screen seams are busted. Has anyone fixed these before? Thank you for all the help, tips and insights!
